On the evening of June 27, Guangsheng Co., Ltd. (hereinafter referred to as “the company”) announced that the company’s wholly-owned subsidiary, Xiamen Hahaide Enterprise Management Co., Ltd. (hereinafter referred to as “Ha Had”), planned to acquire Chongqing Junmei for 39.78 million yuan. Medical Beauty Hospital Co., Ltd. (hereinafter referred to as "Junmei Hospital") 51% equity, to cut into the medical beauty industry.

The medical market prospects need not be said, and beauty has become a leader in female consumption in recent years.

In fact, LED has achieved a lot of development in the field of big health.

LED red and blue beauty hair

According to research, the use of high-energy blue light with LEDs between 400 and 420 nm for the treatment of acne; the use of yellow light near the wavelength of 570nm or red light near the wavelength of 630nm to illuminate the skin, so that the skin is younger.

Actress Fan Bingbing liked to share her favorite beauty products before. Some time ago, she frequently planted grass for everyone in Xiaohongshu, and also created a beauty instrument brand FANBEAUTY.

In addition, some of the LED masks previously reported by China's optical network, in Jingdong crowdfunding, we can also see many beauty equipment using red and blue whitening skin.

Product prices range from a few hundred to thousands.

In addition to the products for the beauty of actresses, in fact, LEDs have also been studied in the issue of hair loss that men are more concerned about. We searched for Taobao, we can see that the price of LED hair dryer is staggering compared to actress beauty products.

UV sterilization

Ultraviolet rays are generally classified into three types according to the wavelength: long-wave ultraviolet rays having a wavelength of 315 nm to 380 nm are abbreviated as UVA, medium-wave ultraviolet rays having a wavelength of 280 nm to 315 nm are abbreviated as UVB, and short-wave ultraviolet rays having a wavelength of 200 nm to 280 nm are abbreviated as UVC. Most of the currently commercially available UV disinfection lamps are UVC-sterilized. Ultraviolet rays can kill a variety of microorganisms, including bacterial propagules, spores, mycobacteria, viruses, fungi, rickettsia and mycoplasma, and have a broad spectrum.

However, UV sterilization has often been used in restaurants, hospitals, etc., and the penetration rate in the home is very low.

However, with the improvement of people's living standards, people pay more attention to health. UV sterilization will inevitably have a place in household consumption. In recent years, we can see that air purifiers, water purifiers, and UV deodorizers are increasingly recognized by consumers, and the average price of these household appliances is generally not low.

On June 12, the US company BOLB announced an external quantum efficiency (EQE) of 12.2% on a fully transparent deep ultraviolet light-emitting diode (UVC LED). This key fundamental technology breakthrough paves the way for UVC LEDs to achieve near-visible LED efficiency in the next few years, and will further expand the application of UVC LED sterilization technology in people's daily lives.

At this year's Guangya Exhibition, Seoul Semiconductor also demonstrated its research and development of UV sterilization in smart toilet water sterilization, kitchen cutting board sterilization, air purifier sterilization, air conditioning purification and other applications, for the current young consumer groups are very Great attraction. Some large domestic lighting companies are also interested in working together on these applications to promote smart home life.

Finally, in the summer, the mosquito killer has once again become a hot commodity. Wavelengths of 365 nanometers have long been a selling point for products.

UV anti-mosquito? This time we have to ask a question mark.

There are many factors that attract mosquitoes. Among them, carbon dioxide is the most important factor for mosquitoes to find prey, followed by odor. Ultraviolet lamps and blue light lamps can only be placed behind them. Therefore, in the face of mosquito killers and human bodies, the choice of mosquitoes will not be basically An error occurred.

Experts said: "The UV-killing lamps currently in normal use are generally composed of ultraviolet light-emitting tubes and high-voltage power grids. Ultraviolet light traps mosquitoes. When mosquitoes touch the outer high-voltage grid, they are instantly killed by electric shock. When people use ultraviolet rays to kill mosquitoes. When the light is on, you can often hear the popping sound. This is because the instantaneous high voltage kills the sound of the mosquito."

It can be seen that "the ultraviolet rays in the mosquito killer cannot kill the mosquito" is true. At best, UV light can only act to attract mosquitoes, and this kind of attraction can also be interfered by the human body and other light sources.

At present, the general ultraviolet mosquito killer has a wavelength of 365 nm and belongs to the longer wavelength UVA band. This band has a strong UV penetration ability and can penetrate most transparent glass and plastic. If we follow the daily UV protection standards, sunglasses should be prepared within 1 meter, and the sunscreen should be applied.

In the past few years, LED blue light, stroboscopic, glare and other issues have been a concern for consumers, these may be some negative aspects brought about by the LED revolution. However, how to use LED to bring health and beauty to human beings may be an area where the lighting industry needs further research and development in the future.
